IMPRO'VMENT IN' CHURN-DASHER..

The Schedule referred to in these Letters Patent and making pari: of the same:

I, THEoPHILUs CRUTCHER, in the town of Edgeeld, county of Davidson, State of Tennessee, have invented certain Improvements in a Churn-Dasher, of

which the following is a specification.

Nature and Objects of the Invention.

The firstpart of my invention relates to the shape of the dasher, with its attachment to the tinv tube; the second part relates to the arrangement of the valve between screws by means of which the air is lintroduced intov the milk. i

Description o f `Drawing.

Figure 1, vie'W from the bottom, perspective. Figure 2, as seen from the front.

Figure 3, perspective, from the top.

Figure 4, as seen from the bottom.

General Description;

screw, E, which receives a male screw, Ifyvthe screws ,being designed toenclose the valve g. The dasher h is made of tin, and'funnel-shaped,

which facilitates its np-and-down movements; it `is perforated with holes and attached to the male screw F.

As the dash is being raised, the air from above opens the valve y, and admits the air as it is forced downward, the valve closes, which forces the air into the milk, at the same time the milk is thrown in jets through the perforated holes in the dash.

The tube I, which is continued to the lowerpart of the dash, and securedv by the wires K K, is intended to keep the air from escaping when the dash isvraised, except through the milk.

I do not claim as my invention the principle of vforcing air into the milk by means of a valve but What I claim as my. improvement, and desire to secure by Letters Patent, is y The combination ofthe conical dasher h, when provided with perforations, as shown, cross-bars k k k k,

the tube c', hollow shaft b, valve-seat c, and valve g, as

herein set forth.
